VALVE FOR TANK CARS.

Application filed May 17,

To all whom iii-may concern: Be it known that I, ALLEN E. OSTRANDER,residing at Ridgewood, county of Bergen, State of New Jersey, and beinga citizen of the United States, have invented certain new and usefulImprovements in a Valve for Tank Cars, of which the following is a full,clear, and exact description, such as will enable others skilled in theart to .which it appertains to make and to use the same, reference beinghad to the accompanying draw ings, which illustrate the preferred formof the invention, though it is to be understood that the invention isnot limited to the exact details of construction shown and described,

as it is obvious that various modifications thereof within the scope ofthe claims will occur to persons skilled in the art.

In said drawings:

Figure 1 is a "broken view, partly in section and partly in elevation,showing my improved discharge valve for tank cars; and

Figure 2 is a section taken on the line 2 2 of Fig. 1.

It is the object of my invention to provide an improved valve for thedischarge outlets of tank cars of the type that is positively seated bya screw means that allows play between the valve and its seat sufiicientto permit of grinding the valve to its seat.

In the drawing,1 designates a car tank of which but portions are shown,having a bottom sheet 2, a top sheet 3 and a dome 4 secured to the topsheet 3.. I

Secured to the bottom sheet 2, by rivets 5, is a flanged dischargeoutlet casing 6 having the usual breakage groove 7 and screw threaded atthe bottom to receive the usual cap, (not shown). The outlet casing 6'isprovided at. its upper end with a valve seat 8 that faces into the tankand in the length of the casing 6 are the grooves 9, diametricallyopposite tO-each other and extending for a short distance as shown inFig. 1. In

order to providethe proper thickness of metal in the casing wall, thecasing is ribbed throughout the length of the grooves, as at I 10 inFig. 2.

Coacting with the seat 8 is a valve 11 provided with an upwardlyextending collar 12 in which is secured, by the pin 13, a valveoperating shaft 14: provided with a hand wheel 15 and guided by thebracket 16 secured to the tank dome 1. Projecting downwardly from thevalve 11 are the guides 17 1920. Serial No. 381,946.

bar 21, the lower end of rod 19 is provided with a retaining collar 22held in place by I the cotter pin 23. I

In use, operation of the hand wheel 15 causes the shaft 14 and valve 11to rotate,

thus rotating the screw threaded rod 19.-

Rotation of the rod in one direction will cause the cross-bar 21 to beadvanced along the rod 19 until it engages theupper ends ofthe grooves 9and further rotation in the same direction, with the cross-bar 21engaging theends of the grooves 9, will cause the valve 11 to be forcedto its seat 8 with suifieient pressure to clear the seat 8 of much ofthe foreign matter that gathers there when the tanks are in service.Rotating the hand wheel in the opposite direction will cause thecross-bar 21 tobe advanced along the rod 19 towards the bottom of thegrooves 9, freeing the valve 11 if it is seated. By rotating the handwheel 15 until the crossbar 21 is away. from both ends of the gr o"oves,sufficient play is given so that the valve 11 may be lifted clear of theseat 8 and rotated so that different parts of the valve and seat willengage when the valve is replaced on its seat in the usual mannerof'grinding a valve to its seat. Continued rotation of the hand wheelafter the crossbar 21 engages the bottoms of the grooves 9 causes thevalve 11 to be lifted from its seat and give a clear passage for thedischarge of the contents of the tank.

. What I claim is:

1. In a tank car discharge valve, a discharge outlet casing having avalve seat and a plurality of grooves, a valve for said seat, operatingmeans for said valve, means mounted in said grooves for reciprocatorymotion therein and adapted to support said valve in the openpositionthereof and a connection between said valve and said meansadapted'to force said valve and said means into engagement wlth saidcasing.

2. In a tank car discharge valve, a I

movement therein and means pivotally con-' nectingsaid cross bar andsaid valve adapted to move said crossbar to the limit of its movement insaid discharge passage and then to force said valve from its seat uponrotation of said valve.

4, In a tank car discharge valve, a casing having a valve seat and adischarge passa e, a valve for saidseat, operting 'means For said valve,grooves in said casing wall open "to said discharge passage, a cross-baradapted to reciprocate in said grooves-and a connection between saidcross-bar and said valve adapted to forcesaidcross-bar against the endsof said grooves and to move, said valve with respect to said valve seat.

5. In a tank car discharge valve, a casing having a'valve seat and adischarge passage, a valve for said seat, operating means for saidvalve, grooves in said. casing wall open to said discharge passage, across-bar mounted in said grooves and a rod joinin .said crossbarandsaid valve and pivota y connected to, said valve. e e

' 6.

7 In a tank car discharge valve, a casing having a valve seat, a valvefor said seat, a screw threaded rod pivotally connected to said valve,grooves in said casing wall, means engaging said screw threaded rod andadapted to reciprocate in said grooves and means adapted to rotate saidvalve to cause relative movement of said valve and saidgroove engaging,means. i

8.
